India summoned the Pakistani High Commissioner, Abdul Basit on Wednesday following an attack on an Indian army base in Kashmir that killed 18 soldiers.

Indian Foreign Ministry officials say they offered to provide evidence for a probe by Islamabad into the incident and asked Pakistan to live up to its commitment to refrain from supporting and sponsoring terrorism against India.

India has blamed the cross-border militant assault on Pakistan-based militants. Islamabad has denied any involvement in the attack.

An Indian army soldier arrives at the army base which was attacked by suspected rebels in the town of Uri, west of Srinagar, Indian-controlled Kashmir, Sept. 18, 2016.

The Foreign Ministry told the Pakistani High Commissioner it could provide fingerprints and DNA samples of the four terrorists who were killed in the attack in Uri on Sunday as well as that of militants who were killed in another attack on an Indian air force base in January.

Indian officials said that items recovered from the site of the attack like grenades, food and medicines have all been made in Pakistan.

Sunday’s attack has fueled anger in India and heightened tensions between the two countries. Indian Prime Minister Narendra Modi has said that it that the assault will not go unpunished.
